Decided on a path to run the antenna wires down from the instrument panel into the cabin. The path is down the firewall to the outer sides of the floor on either side of the plane. On the pilot side, I've routed the Marker Beacon, Com2 and Nav2 antenna leads. On the copilot side, I've routed the 430 GPS, Com1, and Nav1 leads. I drilled three holes for each set through the spar webs and mounted plastic bushings to prevent wire chaffing. On the firewall, I added brackets to hold additional bushings as attachment points for the leads along the way. Antennal leads will be covered by the floor protection, whatever that may be. Terminated the antenna leads to connectors as needed. The com leads were terminated with male BNC connectors. The nav and marker beacon leads were terminated with female bulkhead mount BNC connectors. These were mounted to the outside wall at the wing roots.
